Description
Reference-Grade Precision. Holographic Imaging. Compact Power.
The RBH Reference 61-SF/R is a tour de force in compact, two-way passive speaker design. Engineered for the most demanding audiophiles and home theater purists, this standmount speaker delivers the breathtaking clarity and deep, three-dimensional soundstage of a massive tower system while maintaining a room-friendly footprint.
Hand-assembled in the USA, the 61-SF/R features RBH’s elite Reference upgrade package. By combining an ultra-fast Air Motion Transformer (AMT) ribbon tweeter with a proprietary reference-grade aluminum mid-woofer, this speaker provides absolute acoustic transparency, pinpoint imaging, and an incredibly natural tonal balance.
Elite Reference Driver Technology
The “Reference” moniker represents a major architectural upgrade, replacing standard components with RBH’s most prestigious, state-of-the-art transducer technologies:
-
Proprietary Reference AMT Tweeter: Squeezing air rather than pushing it like a traditional dome, the high-velocity Air Motion Transformer (AMT) ribbon tweeter delivers a lightning-fast transient response. Enjoy effortless, airy, and shimmering high frequencies up to 40kHz with near-zero distortion or ear fatigue.
-
Reference Aluminum Woofer with Solid Phase Plug: The 6.5-inch anodized aluminum cone is equipped with a machined solid metal phase plug in place of a standard dust cap. This critical upgrade eliminates cone-resonance coloration, dramatically improves off-axis midrange dispersion, and acts as a heat sink to keep the voice coil cool under heavy dynamic loads.
-
Inert, Heavyweight HDF Cabinetry: While most bookshelf speakers utilize cheap, resonant MDF, the 61-SF/R is constructed from heavily braced ¾-inch High-Density Fiberboard (HDF). This rock-solid, deadened cabinet eliminates unwanted “boxy” vibrations, ensuring you only hear the pure, uncolored output of the drivers.
-
Modular Upgrade Path: True to RBH’s design philosophy, the 61-SF/R serves beautifully as a standalone high-end stereo monitor. Down the line, it is perfectly size-matched to couple directly on top of the RBH 88-MS dual-8″ subwoofer module, transforming your setup into a colossal, full-range modular tower.
